Ultrasonic Flow Meters at the Highest Level - Flowmax 42i

Ultrasonic Flow Meters - Flowmax42i

Flowmax 42i is a flow meter calculating the volume flow of liquids. Based on the ultrasonic technology Flowmax 42i is able to measure conductive and non-conductive liquids contact free. This model has no moving parts and is absolutely free of wear. Flowmax`s design of the pipe minimizes dead space over the whole geometry. All parts having contact to the medium are PE-HD. Thanks to its technical properties this flowmeter is able to measure all kinds of liquids like: DI-Water, Body care liquids, Cosmetics, liquid food, and also aggressive and/or toxic acids and alkalis. You can characterized flowmax by its high measurement accuracy and repeatability. It have empty pipe detection. Optionally Flowmax has a PID controller function and the calculated flow is provided with a response rate of a few milliseconds on the outputs.

The model has by default a preset quantity counter. The start signal can optionally be fed from the outside and the control signal for activation of the pump or valve control is also standard.

Flowmax 42i is suitable for operation with piston diaphragm and peristaltic pumps.
